Request-tan, also known as Mail-tan or Post-tan in the beginning, is an adult caucasian woman with red hair in a voluminous bobcut, grey eyes with thick red eyebrows and long eyelashes styled to look like a letterbox flag, full lips, and arrow-shaped golden earrings. She wears an ornate brown postman's hat with a red rim, golden studs and rings, a postman symbol on the front and the infinity logo on the back, and even a little letterbox flag on the side. Her usual work outfit consists of a white sleeveless shirt, a small scarf that doubles as a necktie, a red buttoned skirt, and her purple postman satchel with golden accents, including a golden infinity logo. No information exists on her footwear, but in addition to her clothing she applies dark nail polish to her fingernails.
Request-tan may appear a little absent at times, but she's fully dedicated to her job. She spends every drawthread sorting the good from the bad requests and makes sure any deliveries find their way back to the original requester. Alhough the occasional lack of good requests can be frustrating, she's still happy whenever she sees a new request come in.
